Letters Patent No. 85,368, dated December 29, 1868.

.l'-MPRQVEMENT IN SEPARATORS FOR THRESHING-MACHINES.

The Schedule referred 'to in these Letters Patent 351'} making part of the same.

To all whom 'it may concern- Be it known that I, Tomas CRUMLIXG, of Cross- Roads, in the county of York, and State of Pennsyl Vania, have invented a new and improved Separator for Threshers; and 1 do hereby declare that the following is a full, clear, audexact description of the construct-ionand operation of the same, reference being had to the accompanying, drawings, (making a part of this specification,) in which- Figure l is a side elevation, one end ofthe shed'on the front part of my separator being removed.

Figure 2 is a plan view.

This invention is intended for an attachment to a threshing-machine, and has for its object to separate straw from grain after both have passed through a threshcr.

It consists of the common form of straw-carriers-'- that composed of alternate vibrating reciprocating beams, operated by crank-shafts, in combination with areciprocating winnowing board, and a series of suspended fingers between the said beams, for the purpose of preventing the escape of straw in the wrong direction.

In the drawings- A represents the sides, and

B, the bottom of an ordinary winnower, transversely of which, one at each end of the winnowei's, pass two shafts, I) b, with reverse cranks, the cranks of one shaft corresponding with 'those 'of the other, and each pair .of shanks being connected by a beam, 0, said cranks and beam constituting the ordinary straw-carnor. 7 The shaft b is rotated by means of a crank-wheel,

I), and communicates motion to the shaft b through the wheels (1 cl and belt a.

'lrans\'crsely between the legs h It of the winnower, passes a shaft, 'i, to one end of which, outside/0f the leg h,-is rigidly attached the lower extremity of a connecting-rod, II, which has a slot, 7 at its upper .end,

through which passes a pin, 1, projecting from the side of the wheel d, by means of which wheel, pin, slot, and Connecting-POLL.ml oscillating motion is imparted to the shaft t, which motion is"communicatedfrom said shaft to the winnower B through a connecting-rod, not shown, rigidly attached to the shaft t, and jointed to the under side of the winnower.

On the front end of the winnower, is a small shed, G, with a roof sloping toward the carrier, in order to receive the straw from the same.

To prevent any straw from passing of? under the roof, fingers, d, are hinged to the roof of the shed O, and hung between the beams 0.

After the straw has passed through the thresher, it

falls upon the beams c, and-is by them conveyed away,- such kernels of grain as may have passed through with it falling through upon the winnower B, and passing through the holes in that to a receptacle beneath.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-- 'lhc straw-carrier b b c, in combination with the winnowcr B, the fingers (I, the connecting-rod k, and shaft 1, as and for the purpose specified. V
